NN Asks: What did you learn from ANS’s Nuclear 101?
Mike Harkin
When ANS first announced its new Nuclear 101 certificate course, I was excited. This felt like a course tailor-made for me, a transplant into the commercial nuclear world. I enrolled for the inaugural session held in November 2024, knowing it was going to be hard (this is nuclear power, of course)—but I had been working on ramping up my knowledge base for the past year, through both my employer and at a local college.
The course was a fast-and-furious roller-coaster ride through all the key components of the nuclear power industry, in one highly challenging week. In fact, the challenges the students experienced caught even the instructors by surprise. Thankfully, the shared intellectual stretch we students all felt helped us band together to push through to the end.
We were all impressed with the quality of the instructors, who are some of the top experts in the field. We appreciated not only their knowledge base but their support whenever someone struggled to understand a concept.

With reference to loss-of-coolant accidents in light water reactors, the critical flows of subcooled liquids are examined, particularly from the viewpoint of the time extension of the metastability state. “Ad hoc” tests have outlined an upper limit of this time range at 10−4 s. The flow characteristics of the unbounded jets have been investigated both externally (via photographic measurements of the external shapes at various subcoolings) and internally (via pressure profiles in the radial direction). As far as pressure profiles within the jet are concerned, the presence in the jets characterized by the subcooled inlet conditions of a central liquid core gradually evaporating has been outlined.
